Abstract

A method and system for detecting fraud in a telecommunications network matches information on individual calls to a series of rules (18). For each rule (r), a threshold (Tr) is defined, and if the fit of an individual call to that rule is better than Tr an alarm is generated. All call records resulting in alarms are stored within a positive matching file. Likewise, calls which just fail to meet the criteria, within a given tolerance level .THETA., are stored in a separate negative matching file. The entries in the positive and negative matching files are then checked by skilled operators to determine which in fact represent true fraud. On the basis of those validations, a decision module within the system automatically calculates and implements the necessary changes to the thresholds (Tr) by means of a feedback loop.
